COIN-CONTROLLED VENDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 780,628, dated January 24, 1905. Application filed June 25, 1904. Serial ITO-214,202.

' of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to vending-machines such as are controlled by deposited coin, and

has for its object to improve the same in the several particulars hereinafter noted.

The invention consists of'the novel devices and combinations of devices hereinafter described, and defined in the claims.

Theinvention is illustrated in the accompa: nying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a view in' front elevation, showing the vending-machine embodying the features of my invention. Fig. 2 is a vertical section taken from front to rear of the machine on the line m m of Fig. 1. Fig. 3 is a horizontal section taken approximately on the line m of Fig. 2, someparts being broken away. Fig. 418 a detail in section on the line 00 m of Fig. 3. Fig. 5 is a view of the machine in rear elevation with some parts removed and with some parts broken away; and Fig. 6 is aview similar to Fig. 5, but illustrating'different positions of the parts.

, The numeral 1 indicates a suitable case or cabinet which, as illustrated, is formed .with display-compartments 2, with a mechanismcompartment 3, and with a drawer-compartment 4:. Also, as shown, the display-compartments 2 are closed by a removable door 5, having a glass pane 6. The mechanism-compartment 3 is closed by a removable door 7, and the compartment 4 is provided with a drawer 8 for purposes which will presently appear.

Extended vertically within the compartment 3 is a magazine 9, which is adapted to contain -a plurality of checks or tickets 2, placed in a stack one on top of the other. The bottom of the magazine 9 terminates above the bottom of the compartment 3 a distance approximately equal to the thickness ofone of the checks 2, and the bottom check is adapted to be discharged out from under the stack and from the magazine through a slot 10, cut in one side of the case 1, as best shown in Fig. 6.

Within the compartment 3, rigidly secured to the bottom thereof, is a rectangular bearing-frame 11, and rigidly secured to the bottom of said compartment is a channel-like guide 12, in which works a sliding check-ejector 13, the end of which is adapted to work under the magazine and to force the lower check 2 out through the slot 10. (See Fig. 6.) 4 A plunger 11, which is mounted to slide horizontally and parallel to the ejector 13, is connected to said ejector byan arm 15. A spring 16, attached .to the bearing-frame 11 and to a short arm 17 on the plunger l4,yieldingdraws said plunger and said ejector 13 to their extreme positions toward the right with respect to Figs. 5 and 6. The numeral 18 indi cates cushioning-washers, of rubber or leather, which are loosely placed on the plunger 14. The arm 17 at its upper end is pronged or notched and straddles a flange 11 of the bearing-frame 11, thereby holding the plunger-14 against rotation.

An operating plunger or bolt 19, which at its outer end is shownas provided with a operating-knob 20, works through one side of the case 1 and through one end of the bearing-frame 11 and is rigidly attached to a head 21, which in turn is mounted to slide on the plunger 14, and is formed with a depending leg 22, that straddles a flange 11 of the frame 11 and is further guided thereby. The leg 22 is preferably formed with a stop-lug 22, which engages with a lug'll of the flange 11 to limit the movement of the head 21 and operating-bolt 19 toward the left with respect to Figs. 5 and 6 and toward the right with respect to Fig.3. 7 A coiled spring 23, attached at one end to the frame 11 and at its other end to a projection 21 of the head 21, 'yield IOO a rigidly-secured ratchet-bar 24. Pivoted to the front face of the plunger-head 21 (see Fig. 3) is a combined lock-pawl and coin-grapple 25, the pawl end of which is normally held just above and out of engagement with the teeth of the ratchet-bar 24 by means of a spring 26, shown as secured at one end of said head 21. The pawl 25 has but slight movement, such movement being limited by a slotand-pin connection 27 between the same and the said head 21. The short upturned end of the pawl 25 (see Figs. 3 and 4) is notched to receive the edge of the coin 3 with a lip 25 projecting outward thereof.

For cooperation with the short notched end of the pawl 25 to receive and hold the coin is an adjustable coin-grapple in the form of a short pinching-lever 28, pivoted to the head 21. This grapple member 28 at its free end is subject to an adjusting-screw 29, that works through a lug 30 on the head 21.

Normally the head 21 and parts movable therewith stand in the positions indicated by dotted lines in Fig. 3 and by full lines in Fig. 5. The deposited coin is adapted to be delivered to the grapple members on the head 21 when the said head is in normal position by an inclined coin-delivery spout 31, which opens through one side of the case 1, is rigidly secured thereto, and has its lower end terminated, as best shown in Figs. 3 and 5, in position to deliver the coin to the said grappling members 25 and 28, as already stated.

The numeral 32 indicates a cam-flange, which is formed on or rigidly secured to the frame 11 and extends in horizontal position for engagement with the upper portion of the coin which is carried by the head 21.

The numeral 33 indicates a catch-hopper, which is located in position to receive the coins dropped from the head 21 and to deliver the same through the bottom of the compartment 3 into the drawer 8.

The coin deposited in the spout 31 will be dropped against the upturned short end of the pawl 25 and against the upper end of the grapple-lever 28 and will be caught and held thereby, as already described. Under its own weight and the force of momentum the coin caught as just described will wedge itself between the lever 28 and the upturned end of the pawl 25 and will throw the free end of said pawl downward into action on the teeth of the ratchet-bar 24. Hence when the bolt or plunger 19 and its head 21 are moved toward the right with respect .to Fig. 3 or toward the left with respect. to Figs. 5 and 6 the said pawl 25 will catch on the teeth. of said ratchet-bar and will hold said head 21 and bolt 19 against return movements as long as the coin 3 is held as above stated. When the plunger 19 and head 21 are moved toward the right with respect to Fig. 3, the coin y, which is carried thereby, will be thrown against the driving-stem 17 on the lug 17 of the sliding bolt or plunger 14 and the said bolt, together with the ejector-slide 13, will be moved toward the right with respect to Fig. 3 and toward the left with respect to Fig. 6, thereby ejecting one of the checks .2, as shown in the latter-noted figure. When the plunger 19 and head 21 are moved toward the right with respect to Fig. 3 or toward the left with respect to Fi 6 somewhat farther than shown in the said figures, the cam-flange 32 comes into action on the coin 1 (see Fig. 4) and will force the same laterally out from between the upturned end of the pawl 25 and the upper end of the grapple-lever 28 and causes the said coin to be dropped into thehopper 33, and thereby release the pawl 25 from the ratchetbar 24 and permit the plunger 19 and head 21 to be thrown back to normal positions by the spring 23. The spring 16'serves to throw the plunger 14 and ejector 13 back to normal po sitions as soon as the coin y is forced laterally out of engagement with the driving-stem 17.

From the foregoing description it is evident that the cheek-ejector cannot be operated unless a coin has been deposited between the grapple elements carried by the head 21, and it is further evident that movement having been imparted to the said head and to the check-ejector said parts cannot be returned to normal positions until after the coin last deposited has been forced from an operative position, thereby making it impossible to again operate the cheek-ejector without depositing another eoin. The grapple member or lever 28 is made adjustable, so as to set the device to catch coins of different sizes and denominations, it being of course understood that the coin should drop substantially to predetermined distance between the coin-engaging ends of the members 25 and 28.

The machine above described is capable of being used in a great many different ways. It may, for instance, be used to dispense or deliver checks marked with numbers or other characters which entitle the purchasers to any one of certain articles or of the kind of articles contained in the display-compartments 2. This machine may also be found serviceable for many other purposes, such as selling checks of determined value entitling the person securing them to drinks at a soda-water fountain or elsewhere or for selling tickets generally.

From what has been said it will be understood that themaehine described is capable of modification within the scope of my invention as herein set forth and claimed.

What 1 claim, and desire to secure by Letters Patent of the United States, is as follows:

1. In a machine of the character described, the combination with a magazine for articles to be delivered from the machine, of an ejector for delivering the articles from said magazine, a reciprocating plunger for operating said ejector, a relatively fixed rack, a pawl carried by saidplunger, with one end in po-. sition for action on the teeth of said rack, but normally held out of action thereon, the other end of said pawl serving as a coin-grapple, a cooperating coin grapple carried by said plunger adapted to receive the coin, and the said pawl-grapple being thrown into action on said ratchet-bar by a deposited coin, a driver carried by said ejector, and positioned in the path of movement of a coin held by said grapples, of means for forcing said coins from said grapples, under movement of said plunger; and means for delivering the coin to the said grapples, substantially as described.

2. In a machine of the character described,
